Question

我正在尝试将数据库表与数据网格绑定，但是我在代码sda.fill(dt);的第35行遇到问题，但是在第35行却遇到异常

“。”附近的语法不正确

代码：

namespace WebApplication1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            SqlConnection cn = new SqlConnection(@"Data Source=192.168.0.61\newsql;Initial Catalog=AIETraining;User ID=AIETrainingAccount;Password=Training@1234");

            cn.Open();
            Response.Write("Connection established");

            SqlCommand command = new SqlCommand("Select * from Gursimran 
            Singh.publishers", cn);

            DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[5] { 
                       new DataColumn("pub_id", typeof(int)),
                       new DataColumn("pub_name",typeof(string)),
                       new DataColumn("city",typeof(string)),
                       new DataColumn("state",typeof(string)),
                       new DataColumn("Country",typeof(string))});

            SqlDataAdapter sda = new SqlDataAdapter();

            using (command)
            {
                using (sda) 
                {
                     command.Connection = cn;
                     sda.SelectCommand = command;

                     using(dt)
                     {
                          sda.Fill(dt);

                          GridView1.DataSource = dt;
                          GridView1.DataBind();
                     }
                }
            }

            cn.Close();
        }
    }
}

尝试以下

Deal with SQL keywords/Space

namespace WebApplication1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            SqlConnection cn = new SqlConnection(@"Data Source=192.168.0.61\newsql;Initial Catalog=AIETraining;User ID=AIETrainingAccount;Password=Training@1234");

            cn.Open();
            Response.Write("Connection established");

            SqlCommand command = new SqlCommand("Select * from [Gursimran Singh].[publishers]", cn);

            DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[5] { 
                       new DataColumn("pub_id", typeof(int)),
                       new DataColumn("pub_name",typeof(string)),
                       new DataColumn("city",typeof(string)),
                       new DataColumn("state",typeof(string)),
                       new DataColumn("Country",typeof(string))});

            SqlDataAdapter sda = new SqlDataAdapter();

            using (command)
            {
                using (sda) 
                {
                     command.Connection = cn;
                     sda.SelectCommand = command;

                     using(dt)
                     {
                          sda.Fill(dt);

                          GridView1.DataSource = dt;
                          GridView1.DataBind();
                     }
                }
            }

            cn.Close();
        }
    }
}

'。'附近的语法不正确
